Silverbeet (Chard) and spinach both contain vitamins K, A, C and lower levels of the B complex, along with minerals including magnesium, manganese, potassium, copper, calcium and iron.

Spinach also contains "glycoglycerolipids”, which are used by plants for photosynthesis, but recent research in laboratory animals has indicated these may help protect the lining of the digestive tract from damage — especially damage related to unwanted inflammation.
